中国科技大学极地环境研究室、中国著名极地科学家孙立广和他课题组最新发现,过去一百年的南极法尔兹半岛海域变暖和海冰退却导致该海域磷虾相对种群密度呈不断下降趋势,而该发现是从对含有毛皮海豹毛序列的粪土层进行氮同位素分析中得出的。南极磷虾是南大洋食物链的关键 The polar environment research institute of China University of Science and Technology and Sun Liuguang, a famous Chinese polar scientist and his group recently found that the relative population density of krill in this area has been declining continuously over the past one hundred years due to the warming of the Antarctic Farin Peninsula and the retreat of sea ice. This finding is based on a nitrogen isotope analysis of a faecal layer containing fur seal hair sequences. Antarctic krill is the key to the Southern Ocean food chain
